Vulnerability Details

CVEID: CVE-2016-2182
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an out-of-bounds write in the TS_OBJ_print_bio function in crypto/bn/bn_print.c. A remote attacker could exploit this vulnerability using a specially crafted value to cause the application to crash.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/116342 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)

CVEID: CVE-2016-6302
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the failure to consider the HMAC size during validation of the ticket length by the tls_decrypt_ticket function A remote attacker could exploit this vulnerability using a ticket that is too short to cause a denial of service.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/117024 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2016-2177
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the incorrect use of pointer arithmetic for heap-buffer boundary checks. By leveraging unexpected malloc behavior, a remote attacker could exploit this vulnerability to trigger an integer overflow and cause the application to crash.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113890 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2016-6306
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by missing message length checks when parsing certificates. A remote authenticated attacker could exploit this vulnerability to trigger an out-of-bounds read and cause a denial of service.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/117112 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2016-2181
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error in the DTLS replay protection implementation. By sending a specially crafted sequence number, a remote attacker could exploit this vulnerability to cause valid packets to be dropped.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/116344 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2016-6304
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by multiple memory leaks in t1_lib.c during session renegotiation. By sending an overly large OCSP Status Request extension, a remote attacker could exploit this vulnerability to consume all available memory resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/117110 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2016-6303
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an integer overflow in the MDC2_Update function. By using unknown attack vectors, a remote attacker could exploit this vulnerability to trigger an out-of-bounds write and cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/117023 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2016-2183
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the DES/3DES cipher, used as a part of the SSL/TLS protocol. By capturing large amounts of encrypted traffic between the SSL/TLS server and the client, a remote attacker able to conduct a man-in-the-middle attack could exploit this vulnerability to recover the plaintext data and obtain sensitive information. This vulnerability is known as the SWEET32 Birthday attack.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/116337 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2016-2178
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the DSA implementation that allows the following of a non-constant time codepath for certain operations. An attacker could exploit this vulnerability using a cache-timing attack to recover the private DSA key.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113889 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2016-2179
DESCRIPTION: OpenSSL is vulnerable to a denial of service. By sending specially crafted DTLS record fragments to fill up buffer queues, a remote attacker could exploit this vulnerability to open a large number of simultaneous connections and consume all available memory resources.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/116343 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
